The reliable and proven Risk based Inspection (RBI) technology process developed by PP SIMTECH (UK), with key guidance from API 580/581 and UK HSE, has been accepted globally as good engineering practice by leading international companies. PP SIMTECH has successfully implemented RBI at BP, Dow Chemicals, GPIC, ADNOC-Fertil, Norsk Hydro, BASF, INEOS.

RBI technology offers oil and petrochemical industries, chemical, fertilizer and power plants the immense benefits of a risk-based approach to inspection which includes an increase in plant availability and cost saving, minimum duration of shutdowns, change in inspection strategies and intervals and improved safety compliance. The RBI team study also improves the team working and communication between all plant departments.

rbiAsyst™, a fully auditable & transparent software system developed by PP SIMTECH, is designed to facilitate the RBI team study and successful implementation of RBI technology process at a plant site.

Reliable assessment and calculation of risk profile of an item, based on its "active" and "potential" Damage Mechanism ensures that the resulting inspection interval for the item is reliably optimized in a safe and cost-effective manner. The approach to risk-based inspection is based on a strong co-operation between the plant personnel and TCR PP SIMTECH experts. The adopted process of guided expert judgment is based on operational experiences and sound technical basis for the evaluation of possible degradation mechanisms.

The hallmark of TCR Arabia – PP Simtech’s RBI technology process is the method used to reliably assess and calculate the risk profile of an item, based on its "active" and "potential" Damage Mechanism identified by the RBI study team, which in turn ensures that the resulting inspection interval for the item is reliably optimized in a safe and cost-effective manner. Operating limits are also defined by the RBI team to prevent increase in damage rate or initiation of a new damage mechanism. Where the business or safety risks are unacceptable, risk mitigating options are also recommended as part of the output.

Benefits of RBI include:

Increased safety and equipment reliability

Fewer planned shutdowns

Fewer unplanned shutdowns

Longer inspection intervals

Potential fewer inspection and maintenance costs

Evaluation of effectiveness of inspection activities

Increased consistency of inspection planning

Identification of potential damage mechanisms

Priorisation of inspection

Identification of key process parameters affecting degradation rates

Assessment of proposed process changes that could impact degradation rates
